[cl-debian] Bug#445299: slime: No LIST-ASDF-SYSTEMS in the SWANK package

[Ingvar]

Here's a partial solution (still not perfect, because this only ends up 
hitting anoter missing function, SWANK:OPERATE-ON-SYSTEM-FOR-EMACS, and that 
one I haven't successfully made to work):

+(defslimefun list-asdf-systems ()
+  (loop for name being the hash-key of asdf::*defined-systems*
+        collect name))

What I (ideally) want to have back is the "load an ASDF-based system, get a 
list of warnings, errors, informational wossnames in a tree-based view, with a 
direct link to where in the source it was signalled from when that is known". 
I suspect that is a bit more than what I currently have working.

However, since it's been in previous versions, I suspect hunting down 
OPERATE-ON-SYSTEM-FOR-EMACS from there might be Just The Thing.
